Title: Vehicle towed apparatus for striping of roads
Inventor: SCHROEDER JAMES C
IPC: B05B9/01
Filed: 1997-04-18
Abstract: A line striper is attached to a vehicle with a two point hitch and has a swivelable rotatable wheel mounted thereunder to support the striper on the ground. A main beam is releasably clamped and may be slid from side to side depending on operator preference. The gun boom may then be located on the desired side. A delay feature on the control allows the operator to look ahead on a sighting camera and pick the point at which he or she desires striping to start (or stop or any other operation).  The controller then compensates for the calibrated distance between the sight point and the spray gun and then starts and stops the gun at the appropriate time given road speed.

Title: Optical switching apparatus and method for use in the construction mode testing of a modular fiber administration system
Inventor: PIMPINELLA RICHARD JOSEPH
IPC: G02B6/44
Filed: 1997-07-31
Abstract: A device and method for connecting an optical switch to the optical fibers that terminate on a fiber distribution shelf within a fiber administration system. The optical switch device contains a support plate that is shaped essentially the same as the protective cover of fiber distribution shelf. As such, the support plate of the optical switch device can be joined to a specific fiber distribution shelf by substituting the support plate for the protective cover. An optical switch is affixed to the support plate, wherein the optical switch is sized not to extend beyond the peripheral boundaries of the support plate. As a result, when the support plate is placed over a fiber distribution shelf, the optical switch joined to the support plate does not obscure any other fiber distribution shelf in the fiber administration system.

Patent CA-2226641-A1 (CA)
Inventor: KORHONEN JARI
IPC: G06F13/26
Filed: 1996-07-10
Abstract: The invention relates to a method and system by means of which a large number of peripheral modules (TRn) can request service from a controller, e.g. in form of an interrupt request.      Congestion of service requests is prevented in advance by assigning a predetermined time slot to each peripheral module (TRn) during which it is allowed to ask for service from the controller. The time slots are coordinated by a time slot counter which is stepped with a clock signal (CLK). The time slot counters of the different peripheral modules are synchronized with a synchronization signal (SYNC). The peripheral modules (TRn) may include subperipheral modules, whereby each subperipheral module can request service independently, or a gate N1 coupled to a register SR1 may be employed for detecting that a subperipheral module requires service.
